System and method of applying adaptive control to the control of particle accelerators with varying dynamics behavioral characteristics using a nonlinear model predictive control technology

Abstract

The present invention provides a method for controlling nonlinear control problems within particle accelerators. This method involves first utilizing software tools to identify variable inputs and controlled variables associated with the particle accelerator, wherein at least one variable input parameter is a controlled variable. This software tool is further operable to determine relationships between the variable inputs and controlled variables. A control system that provides variable inputs to and acts on controller outputs from the software tools tunes one or more manipulated variables to achieve a desired controlled variable, which in the case of a particle accelerator may be realized as a more efficient collision.

Description

TECHNICAL FIELD OF THE INVENTION[0001]This application claims benefit of priority to U.S. provisional application Ser. No. 60 / 431,821, titled “System and Method of Adaptive Control of Processes With Varying Dynamics,” filed Dec. 9, 2002, whose inventors were Bijan Sayyarrodsari, Eric Hartman, Celso Axelrud, and Kadir Liano.BACKGROUND OF THE INVENTION[0002]The study of fundamental particles and their interactions seeks to answer two questions: (1) what are the fundamental building blocks (smallest) from which all matter is made; and (2) what are the interactions between these particles that govern how the particles combine and decay? To answer these questions, physicist use accelerators to provide high energy to subatomic particles, which then collide with targets. Out of these interactions come many other subatomic particles that pass into detectors. FIGS. 1A and 1B illustrate typical collisions or interactions used in this study. From the information gathered in the detectors, phys...

Benefits of technology

[0022]Yet another embodiment of the present invention provides a dynamic controller for controlling the operation of a particle accelerator by predicting a change in the dynamic input values to effect a change in the output of the particle accelerator from a current output value at a first time to a different and desired output value at a second time in order to achieve more efficient collisions between particles. This dynamic controller includes a dynamic predictive model for receiving the current input value, wherein the dynamic predictive model changes dependent upon the input value, and the desired output value. This allows the dynamic predictive model to produce desired
